As an avid CFS2 player of more years than I care to remember, I've found Hardware Acceleration won't work with Windows 10/11 and modern GPU's.
A simple workaround is to use DDrawCompat - https://github.com/narzoul/DDrawCompat/releases
Visit the above link, scroll down to the file DDrawCompat-v0.7.1.zip download and extract.
Then you just copy & paste the ddraw.dll into the main CFS2 installation folder.
Voila!
You'll now have full hardware acceleration in CFS2.
This has been tested extensively by myself on both Windows 10 / 1080ti and Windows 11 / 3080ti and it works a treat!
Enjoy.
